Correct answer
D(D)
Step-by-step explanation
Number of radial nodes = n – (l + 1)
For 3s orbital n = 3, l = 0
Number of radial nodes = 3 – 0 – 1 = 2
It is correctly represented in graph of option D.
For 3s orbital n = 3, l = 0
Number of radial nodes = 3 – 0 – 1 = 2
It is correctly represented in graph of option D.
